Compiler options affect the aspects of your program

A compiler-directing statement is a statement that causes the compiler to take a specific action during compilation.

BASIS statement
This extended source program library statement provides a complete COBOL program as the source for a compilation. For rules of formation and processing, see the description of text-name for the COPY statement.

*CONTROL (*CBL) statement
This compiler-directing statement selectively suppresses or allows output to be produced. The names *CONTROL and *CBL are synonymous.

COPY statement
This library statement places prewritten text into a COBOL program. A user-defined word can be the same as a text-name or a library-name. The uniqueness of text-name and library-name is determined after the formation and conversion rules for a system-dependent name have been applied. If library-name is omitted, SYSLIB is assumed.

DELETE statement
This extended source library statement removes COBOL statements from the BASIS source program.

EJECT statement
This compiler-directing statement specifies that the next source statement is to be printed at the top of the next page.

ENTER statement
The compiler handles this statement as a comment.

INSERT statement
This library statement adds COBOL statements to the BASIS source program.

PROCESS (CBL) statement
This statement, which is placed before the IDENTIFICATION DIVISION header of an outermost program, indicates which compiler options are to be used during compilation of the program.

REPLACE statement
This statement is used to replace source program text.

SERVICE LABEL statement
This statement is generated by the CICS translator to indicate control flow, and should be used at the resume point for a call to CEE3SRP. It is not intended for general use.

SKIP1/2/3 statement
These statements indicate lines to be skipped in the source listing.

TITLE statement
This statement specifies that a title (header) should be printed at the top of each page of the source listing.

USE statement
The USE statement provides declaratives to specify these elements:
Error-handling procedures: EXCEPTION/ERROR
User label-handling procedures: LABEL
Debugging lines and sections: DEBUGGING

ARITH: The maximum number of digit positions in the PICTURE clause for packed-decimal, zoned-decimal, and numeric-edited data items is 18 with COMPAT option and 31 with EXTEND option

CICS: The CICS compiler option enables the integrated CICS translator and allows specification of CICS suboptions. You must use the CICS option if your COBOL source program contains EXEC CICS statements and the program has not been processed by the separate CICS translator.

MAP: Use MAP to produce a listing of the items defined in the DATA DIVISION.

OPTIMIZE: Use OPTIMIZE to reduce the run time of your object program. Optimization might also reduce the amount of storage your object program uses. Optimizations performed include the propagation of constants and the elimination of computations whose results are never used. Because OPTIMIZE increases compile time and can change the order of statements in your program, you should not use it when debugging.

MAP: Use MAP to produce a listing of the items defined in the DATA DIVISION.
